Recently, my girlfriend Miki has been taking out her frustrations on me. Our arguments have increased and our relationship has become stale and boring... She seems to be dissatisfied with my indecisiveness and unreliability. Miki shares a room with her best friend Ria. When I went to her room to hang out, she yelled at me even though Ria was there. The only thing that saved me was that the kind Ria was always on my side. They were both supposed to go to a seminar camp, but Ria was absent due to illness, so she asked me to do some shopping for her. When I delivered the things she asked for, something seemed strange. It didn't seem like it was because she was unwell. "Miki, you're cheating on me... A senior who is rich, drives a luxury car, and is reliable... He said he was coming to the training camp too... that's why I didn't want to go with him." His girlfriend suddenly discovered he was cheating on her... "She's too cold to Hideto, and I can't forgive her for betraying him... Even though I liked him first... "I only held back because it was Miki... I can make Hideto happier than you..." Ria kissed me as I was stunned. By now Miki must be cheating on me... Never mind... I felt something snap inside me. Ria's body had a plump, feminine feel and was so comfortable to hold that I felt a sense of security and couldn't let go... "I love you..." It had been so long since I'd had sex that made me feel loved... I was cheating... No, I was serious. My emotions overflowed as I touched Ria's love. For the two days that Miki was away, we fucked and made love like a couple who had just learned how to have sex, completely lost in each other.
